Does myocardial scar assessment provide incremental prognostic value over LVEF for sudden cardiac death risk stratification in patients with nonischemic cardiomyopathy?
Myocardial scar assessment provides incremental prognostic value for sudden cardiac death risk stratification in nonischemic cardiomyopathy, suggesting it should be incorporated into criteria for primary prevention ICD placement.
Myocardial scar and LVEF are both risk markers for all-cause and cardiac death in patients with nonischemic cardiomyopathy. However, whereas myocardial scar has strong and incremental prognostic value for SCD risk stratification, LVEF has no incremental prognostic value over clinical measures. Scar assessment should be incorporated into patient selection criteria for primary prevention implantable cardioverter-defibrillator placement.
